DOORSTOP.

Application filed November To all whom t may conce/Mz- Be it known that 1, ARTHUR E. Moen-no, a citizen of the United States, and a resident of Batavia, in the county of Kane and State of illinois, have invented a new and useful improvement in Doorstops, of which the following is a full, clear, and eXact description.

My invention relates to improvements in door stops, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a door stop which will automatically lock a door in opened position.

A further object of my invention is t-o provide a device of the type described which can be readily att-ached to a door without altering the construction of the latter.

A further object of my invention is to provide ay device of the type described which is simple in construction, inexpensive to manuvfacture, yand efficient for the purpose intended.

()ther objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure 1 is a plan view of the device as shown operatively applied to a door, the door being in opened position,

Figure 2 is a side elevation of the device, portions thereof being shown in section, and

Figure 3 is a plan view of the device as shown applied to a door, the door` being in closed position.

1n carrying out my invention, I provide a door 1 which is secured to a wall 2 by hinges 3. The wall 2 is reenforced by the ordinary means, such as a stud 4. The parts described so far are ordinary in construction and form no part of my invention, except in so far as t-hey cooperate with the parts to be described.

1 then provide a bracket 5 which I secure to the door 1 by screws 6 and 1 also provide a. bracket 7 which is secured to the stud 4 by means of screws S. As clearly shown in Figure 2, the brackets 5 and 7 are provided with lugs 9 and 10, respectively, the lugs being provided with alined vertical openings 11 and 12 therein. An arm 13 is provided with a collar 14 at one end thereof, the collar being pivotally mounted between the lugs 9 by 21, 1921. Serial N0. 516,67.

means of a bolt 15 which is disposed in the alined openings 11 in the lugs 9 and .in the bore 16 of the collar 14. 1n a like manner, 1 provide an arm. 17 which is also provided with a collar 18 at one end thereof, the collar being pivotally disposed between the lugs 10 of the bracket 7. A bolt 19 is disposed in the alined openings 12 of the lugs 10 and in the bore 2O of the collar 18. The arm 13 is provided with a cup-shaped member 21 which has a square tapered recess 22 therein. The uppersurface of the member 21 is also pro vided with an enlarged recess 23 which conimunicates with the recess 22. er pin 24 is provided with a handle 25 and has its lower end 26 made square and tapering so as to be received within the recess 22. The pin 24 has a square recess 2.7 in the upper side thereof and has a central bore 28 communieating with this recess. The free end of the arm 17 is provided with a downwardly projecting pin 29 which is made square for a portion of the length thereof adjacent the arm 17, such as at 80. The square portion SO is adapted to be snugly received within the square recess 27 and the remainder of the pin 29 is adapted to be received within the bore 28.

From the foregoing description of the ya rious parts of the device, the operation thereof may be readily understood. Assume that the door is in closed position and that the lower portion 26 of the pin is not in aline nient with the recess but rides on the lower surface of the recess The door can now be opened and as it is. swung about its hinges 3, the arms '1C- and 1'? swing with respect to each other. thus causing the iower portion 260i' the: pin 24 to be brought into alinernent with the recess when the door 1 is in opened position. Viie weight of the pin 24 will now cause the latter to drop into and to be received by the recess 22. 1t will therefore be appar nt that the door 1 will be held in opened position as long` as desired, since the arms 13 and l! are locked with respect to each other.

. lli/Then the door 1 is desired to be closed` the pin 24 is manually lifted out of the recess 22 by means of the handle 25 as is shown in the dotted lines in Figure 2. rThe door 1 can now be swung into closed position, the lower portion 26 of the pin 24 being instantly thrown out of alineinent with. the recess 22 and thus being permitted to ride freely on the lower surface of the recess 23.

82 in the member 2l. A washer 33 and a nut'V 34 are disposed over the end of the bolt 3l and are carried thereby. The diameter of the washer 33 is slightly larger than the d iameter of the opening 32 and thus secures the pin 29 to the member 21.

This construction prevents the parts of the device from becoming disassembled during transportation.

claim:

l. The combination with a support and a door hinged to said support, of an arm pivotally carried by the door and having a non-circular recess in the outer end thereof, a non-circular locking pin adapted to be received in the recess of said arm and being provided with a non-circular bore therein, and a second arm pivotally secured to said support and having a non-circular projection at the outer end thereof adapted to be disposed in the bore of said pin, said pin being movable on said projection and adapted to be moved out of engagement with the recess of said first named arm.
